When I first saw that a shop in Florida had yanked the low-slung flat-six out of a Porsche Cayman and stuffed in a tall 5.0-liter Ford Mustang V8, I wondered if the car’s handling might be compromised. But now my musings have been answered by Matt Farah and some badass canyon roads.

Truly, we are living in an extraordinary time for nutjob junkyard engineering. As proof, look at this otherwise junky Malaise Era Camaro with a 6.0-liter LS V8 out of a truck with four turbos pulled off Ford Ecoboost engines. It is a monster.

Ryan Tuerck fired up his project car to end all project cars tonight: a Toyota GT86 with a Ferrari 458 engine mounted up front. With a ton of custom parts and clever modifications making it work, we couldn’t wait to hear this one, either. Fortunately, the wait is over. Listen to the glorious noise.

Most people make sleepers out of cars that are already somewhat inclined towards performance modification. Old trucks, old American sedans, that sort of thing. Nobody crams an LSx into a 2007 Kia Sorento.

I think the Dodge Viper (RIP) V10s, all versions of them, are some of the coolest engines ever made and nothing anybody can say will make me think otherwise. You can stick one in your lawnmower, or your 1968 Camaro, and you won’t hear a peep out of me.

Diesel-powered pony cars—so perverse and unnecessary that I have to admit I’m intrigued. The real question is, what’s filthier: the fumes pluming out of these exhaust pipes or the grandiloquence coming out of this narrator’s mouth?

Normally people swap out the rotary engines in their Mazda RX-7s because they want something more simple. A nice chassis, a beautiful design, no more worrying about apex seals. This guy did just that, except the opposite, because he did swap in a conventional piston engine, but he supercharged and turbocharged it.

Four years ago, the Internet gazed upon the glory of a BMW Z4 getting a Viper V10 pulled from a Ram truck crammed up its nostrils. But back then the car was a work in progress. Now the car is complete, and it’s for sale, too.

I love crazy engine swaps, even if they turn a car from daily-drive-able to totally useless. Here’s a Porsche Cayman—a car normally fitted with a mid-mounted, low-slung flat-six— but with a big 5.0-liter Coyote V8 swapped in. It may sound like blasphemy, but just watch how much power this thing makes on the dyno.

Sometimes I am simply overcome with an inexplicable and inexorable automotive obsession. There’s nothing I can do about it. At least, that’s what I’m telling myself having spent the last hour doing nothing but watching videos of RB5s.

We pretty much get the car film format at this point, with the dramatic build up and the slow motion and whatever else. What we need now is more weird vids, like this kaleidoscope edit for Formula Drift’s Matt Coffman.

Earlier this month, we saw a Ferrari 458 engine mounted in the nose of a Toyota GT86. We had no idea how it was supposed to work. But now we have a first look at the build process, like how it will have intakes behind the front wheels.
